An Arabian gas liquefaction company shipped a titanium U-tube (hairpin) heat exchanger to Tube Tech’s UK research and development facility so that our dedicated team could remove calcium carbonate and tenacious silicate deposits from within the fragile tubes to restore heat transfer efficiency.
Scott Donson, Technical Director: “The hairpins were solidly blocked. This level of blockage and hardness factor has always previously meant a re-tube or full replacement. We had to take great care because the heat exchanger was titanium, perhaps the only one of its type that has been restored in this manner.”
Due to bespoke Intellectual Property being deployed, Tube Tech is happy to demonstrate and discuss the unique U-tube heat exchanger cleaning process if further information is required.
A spokesperson for the client said:
“We were very satisfied with the standard achieved. We had tried drilling, high-pressure jetting at 1,000BAR and various chemicals with no joy. Our objective was to unblock 5% of tubes to reach satisfactory performance.
Tube Tech achieved 7% and promised to attain 95%-plus if required. This avoided a full and expensive retube costing at least $250,000. We will have no hesitation in calling in Tube Tech again.”
